Application filed May 18, 1912. Serial No. 698,142.

To all whom it may concern Be itknown that I IBERT BERKowrrz a citizenof the United States, residing at New York, county of New York, State ofNew York,-have invented certain new and useful Improvements inBracelets, of which the following is a specification. I

This invention relates to bracelets and more particularly 'to the typeof expansible bracelet which accommodates itself to the size of theWrist of the wearer and which may be placed in various positions on theforearm and fit snugly in every position.

The principal object of this invention is to produce a bracelet of thistype which is easily and cheaply manufactured and can not easily get outof order.

Further objects and advantages will hereinafter appear.

In the drawing illustrating this invention, Figure 1 is 'a longitudinalsection through several links of my improved eX- pansible brac'elet.Fig. 2 is a perspective View illustrating one of the units of which eachlink is composed. Fig. 3 is a perspec tive view illustrating anotherunit composing each link and cooperating with the unit illustrated inFig. 2. Fig. 4 illustrates a blank from which the unit illustrated inFig. 3 is formed. Fig. 5 is a view similar to Fig. 2 and illustrating amodified form of unit.

Referring to the form illustrated in Figs. 1 to 4, units 1 each consistof two curved bars 4 united by cross bars 5, 6 and 7. Bar 6 is locatedat one end and is reduced relative to bars 4 and forms a continuation ofa shoulder 8 formed longitudinally of bars 4 which constitute a guide onwhich the other unit composing the link is guided. Bar 7 is rounded offand constitutes pivot about which the adjacent unit can turn. The entireunit 1 may be stamped out of flat bar metal and if desired the roundingof bar 7 can be accomplished by hand or any other suitable way.

Units 2- eachconsist of two portions 9 and 10 joined together by areduced portion 11. This unit is inserted into the opening between thebars 4 and turned so that the reduced portion 11 meshes with theshoulders 8. then parts 9 and 10 are bent over in the between bars 5 and7. This slot is of a length equal to the width of the portions 9 and 10,thus allowing free play with the ends 12 and 13 therein. Thetongue 14may then be inserted in the space 15 located at the contiguous end ofthe unit and the two ends may be thus united and preferably swagedtogether so as to form a flush surface. Springs 3 are inserted beforethe parts 9 and 10 are bent over and are positioned between the end 11of unit 2 and bar 6 of unit 1.

It will thus be seen that the units compo-sing each expansible, link arerelatively slidable with respect to each other and are piv oted to thelinks adjacent thereof. By reason of the-guiding means consisting'of theshoulders 8 which Ihave provided for the units of each link. anyderangement of parts of the links is avoided.

In the modified form illustrated in Fig. 5, the bars 4 of unit 1 areunited by cross bars 6* and 7, the latter cross bar being roundedoff-and serving as a pivot for the adjacent link. Shoulders 8 are formedon bars 4 and are reduced so as to be flush with the bar 6. Portions 4of bars 4 are cut awayso as to make room for the ends 12 and 13 whichextend the "full width of units 2'. In this form of unit. it will benoted that the part corresponding to cross bar 5 of Fig. 2 ,is omittedand bar 7 is relied upon to preserve the rigidity of the unit.

1. In a. bracelet, a plurality of expansible links. each link comprisinga unit including two side bars and a plurality of cross bars connectingsaid side bars. said side bars bcing of reduced section adjacent theirinner longitudinal edges to form guides. a second unit interlinked withsaid first unit and slidably guided by said guides and a spring 96Having thus described my invention, I

connecting bar, a second unit having a reduced portion relatively to thebody thereof working bet-ween said sidebars and a lateral portionengaging said shoulder and reduced cross bar and uided thereb and aspring between said reduced portion of the second unit and the reducedcross bar of the first unit. 7

3. In a bracelet, a plurality of links, each link comprising twointerlinked units, one of said units having side barsand a connectingbar intermediate the ends of said side 7 bars, anotherconnec ting, baradjacent one end of the side bars and of reduced section relativelythereto, there being a shoulder formed on one of said side barssubstantially flush with the last mentioned connecting bar, a secondunit having a reduced portion relatively to the body thereof working besaid side bars, the latter having a. shoulder running longitudinallythereof 'andsubstantially flush with said cross bar, a second. cross barat the other end of said side bars and adapted to serve as a pivot forthe adjacent link, a second unit cooperating with said first unit andinterlinked therewith, said second unit havinga reduced end portionworking between saidside bars, said second unit being guided by saidshoulders and said reduced cross bar, the opposite end of said secondunit being-adapted to engage a bar of an adjacent link, and a springbetween said. reduced cross bar and the first mentioned end of thesecond unit.

5. In a bracelet, a plurality of expansible links, one of said linkscomprising a unit having two side bars curved in the direction of theirlength, a cross bar intermediate the ends thereof, another cross bar atone end thereof and reduced in section-With respect to said side bars,the latter having shoulders running longitudinally thereof andsubstantially flush with said cross bar, a third cross bar at the otherend of said side bars and adapted to serve as a pivot for the adjacentlink, asecond unit cooperating With said first unit andinterlinkedtherewith, said second unit having a reduced end-portionworking between said side bars,'of said second unit being guided by said-shoulders and said reduced cross bar, the opposite end of vsaid secondunit being adapted to engage a bar of an adjacent link, and a springbetween said reduced cross bar and the first mentioned end of the secondunit.

6. In a bracelet, a'plurality of expansible links, one of said linkscomprising a unit having two side bars and connecting cross bars, saidside bars being-reduced in section adjacent to theirinner longitudinaledges, a second unit interlinkd with said first uni-t and having areduced portion Working between said side bars and a projecting portionextending over said reduced portions and guided thereby, and a springwithin said second unit and extending between one end thereof and one ofsaid connecting bars, said spring being adapted to be compressed whenthe link is expanded v IBERT BERKOWITZ.
